Abstract
A design method of a metal mask, a manufacturing method of the metal mask and a computer-readable storage medium are provided. The design method of a metal mask includes: calculating amounts of deformations of the metal mask in two directions perpendicular to each other based on a stretching force of the metal mask in use and deformation properties of the metal mask in the two directions; and compensating the deformations of the metal mask in the two directions by compensation amounts for the deformations, which are identical and opposite to the amounts of the deformations of the metal mask in the two directions, respectively.
